For more information of "Consistent Rotation Based Formulation", see the section below.
- CRBF stands for Consistent Rotation Based Formulation.
- It is a method used in computational mechanics to solve problems involving large deformations and rotations.
Meaning of CRBF
- CRBF is a numerical method that uses a set of shape functions to represent the displacement field of a deformable body.
- The shape functions are based on the concept of consistent rotations, which ensures that the displacement field is compatible with the rigid body motions of the body.
How does CRBF work?
- CRBF involves the following steps:
- Discretize the deformable body into a set of finite elements.
- Define a set of shape functions for each element that satisfy the consistent rotation condition.
- Use the shape functions to interpolate the displacement field within each element.
- Assemble the element contributions to obtain the global displacement field.
Advantages of CRBF
- CRBF offers several advantages over traditional methods, including:
- Accurate representation of large deformations and rotations.
- Mesh-free formulation, eliminating the need for mesh generation.
- Robustness and stability in handling complex geometries.
